A casement window is a type of window that opens outward on side-mounted hinges. These windows have been around for centuries, but the modern iteration was popularized by the English architect and designer John Belcher in 1877.
Replacing glass in a casement window can be done with some basic tools and knowledge. This article will help guide you through the process of replacing your own glass pane, from measuring correctly to finding suitable replacements.
Tools Needed
Before beginning the replacement process, it’s important to make sure you have all of the necessary tools available. The following items are needed:
• Putty knife or razor blade
• Screwdriver
• Caulking gun and sealant
• New glass pane in the correct size
• Glazing points or glazing clips
1. Preparing the Window Frame
Before replacing the glass, you’ll need to remove any existing putty and clean up the frame. To do this, use a putty knife or razor blade to carefully scrape off the old putty. If necessary, you can use a solvent such as paint thinner to help soften it.
Once all of the old putty has been removed, use a damp rag to wipe down the inside edges of the window frame where new glazing will be applied. Allow it to dry completely before proceeding.
2. Removing the Old Glass
Once the frame is prepared, you can remove the old glass by carefully prying it out of the window frame with a putty knife or other flat tool. Be sure to wear safety glasses and thick gloves when doing this in order to protect your eyes and hands from broken glass.
It’s also important to be careful not to damage the window frame itself by using too much force or sharp tools. Once all of the pieces of glass have been removed, use a vacuum cleaner or broom to clear away any remaining shards.
3. Installing New Glass
Now that you’ve cleared away any remaining shards of glass, you’re ready to install the new glass. If the window frame is metal, you can use an adhesive caulk to attach the new glass pieces to the frame.
However, if the frame is wood, you’ll need to purchase a special type of glazing putty for attaching the glass. Once this has been applied around all edges of the replacement glass, you can then press it firmly into place in the window frame.
4. Caulking Around The Glass
Once the new replacement glass has been installed in its proper position, it’s time to apply caulk around all of its edges in order to ensure that any air gaps or drafts are eliminated.
Use a caulking gun and high-quality silicone caulk for this task be sure not to skimp on the quality of the caulk, as it is essential to a successful glass replacement job.
It’s recommended that you begin by applying a small bead of caulk along both sides of the window frame, then press down lightly along each side so as to compress the caulk into place and ensure even sealing all around.
Work your way around the entire perimeter slowly and carefully in order to avoid any air pockets or gaps.
Once completed, you can use a damp cloth or rubber gloves to smooth out and evenly spread the caulking material around the edges of the glass.
5. Finishing Touches
Once all aspects of the project are finished including cleaning up any excess glue or grout that may be present you can reinstall the window hardware and open the casement window.
With a bit of luck, your new glass installation will be successful and it’ll feel like no time had passed since taking out the old pane.

FAQs
What type of glass is best for a casement window?
The type of glass you should choose depends on your needs and preferences. Generally, tempered or laminated safety glass is the best option for casement windows as it provides an added layer of protection from potential breakage and impacts. It’s also often thicker than standard glass, helping to provide extra insulation against outside temperatures.
How do I measure the size of my window for a replacement glass pane?
It’s important to take precise measurements when replacing the pane in your casement window so that you get one that fits perfectly. Begin by measuring from top to bottom and side to side both the inside and outside frames, then determine the size of the glass you’ll need. It should be a 1/8-inch wider than the opening and at least 1 inch longer on each side.
What type of glass should I use?
The most common types of replacement glass used in residential casement windows are tempered and laminated. Tempered glass is a great option if you’re looking for durability and protection from potential breakage and impacts.
It’s also often thicker than standard glass, helping to provide extra rigidity to the window. Laminated glass is another great choice for casement windows, as it’s made from two pieces of glass held together with a plastic interlayer in between. This helps provide additional protection against impacts and breakage, while also helping to reduce sound transmission into your home.
Q: How do I prepare the old window for the replacement glass?
Preparing your casement window for replacement glass is critical to ensuring a successful installation. First, you’ll want to use a putty knife or other scraper to remove any existing glazing compound from around the pane. This will create a clean surface for the new glass to sit on.
Then, you’ll need to carefully remove the old glass without damaging the frame or other components of the window. This is typically done by using a specialized tool called a glass cutter which can be purchased at most hardware stores.
